Emotional faces capture spatial attention in 5-year-old children

Emotional facial expressions are important social cues that convey salient affective information. Infants, younger children, and adults all appear to orient spatial attention to emotional faces with a particularly strong bias to fearful faces. Yet in young children it is unclear whether or not both happy and fearful faces extract attention. Given that the processing of emotional faces is believed by some to serve an evolutionarily adaptive purpose, attentional biases to both fearful and happy expressions would be expected in younger children. However, the extent to which this ability is present in young children and whether or not this ability is genetically mediated is untested. Therefore, the aims of the current study were to assess the spatial-attentional properties of emotional faces in young children, with a preliminary test of whether this effect was influenced by genetics. Five-year-old twin pairs performed a dot-probe task. The results suggest that children preferentially direct spatial attention to emotional faces, particularly right visual field faces. The results provide support for the notion that the direction of spatial attention to emotional faces serves an evolutionarily adaptive function and may be mediated by genetic mechanisms.     

A meta-analysis and systematic review of reactivity to judgements of learning

Judgements of learning (JoL) are often used in memory research as a means for assessing an individual’s metacognitive beliefs about their learning. JoL have been shown to reliably predict performance as well as learning behaviours and decisions . Participants may, however, modify their behaviour in response to performing JoL. There has, however, been little consensus as to the reliability and direction of the effect. We report on a meta-analyses that assesses the evidence that memory performance is reactive to JoL. The results indicate that overall providing JoL does not have a significant effect on memory performance (g?=?0.054, 95% CI ?0.027 to 0.135). However, sub-groups analysis showed that this effect depends on the nature of the stimuli to be recalled, with moderate positive reactivity observed for related word pairs (g?=?0.323, 95% CI 0.083 to 0.563) and word lists (g?=?0.384, 95% CI 0.146 to 0.622) but no reactivity when pairs were unrelated or a mixture of related and unrelated pairs. These results indicate that researchers should be aware that eliciting JoL may well influence participants’ underlying encoding processes, especially when using related word pairs or word lists.

Grade differences in reading motivation among Hong Kong primary and secondary students

Background Most previous studies in Western societies have demonstrated a general decline in school motivation. However, it is not clear whether motivational decline occurs uniformly for all students. The moderating effects of individual and cultural differences on students' motivational decline need to be further explored. Aims This study aimed to examine the grade differences in students' reading motivation, including self‐efficacy, intrinsic motivation, extrinsic motivation, and social motivation, in a Chinese educational context. Grade by gender and grade by school‐average achievement interactions were also checked to explore the role of individual differences in students' motivational changes. Sample A total of 1,794 students (860 boys and 934 girls) volunteered to take part in this study, of whom 648 were Grade 4–6 students from 11 primary schools, 627 were Grade 7–9 students from 12 junior secondary schools, and 519 Grade 10–11 students from 6 senior secondary schools. Method A Chinese version of the Motivation for Reading Questionnaire (CRMQ) was administered to all participants during regular class periods by their teachers. Reliability analyses and confirmatory factor analysis (CFA) were first undertaken to assess the psychometric quality of the CRMQ. Then, multisample CFA was conducted to examine whether the factor structure of the CRMQ was equivalent across students at different grade levels. Grade differences in various reading motivation constructs as well as grade × gender and grade × school‐average achievement interactions were examined using multiple‐indicator‐multiple‐causes modelling. Results The findings of this study supported the reliability and the factor structure of the CRMQ in measuring the reading motivation of Chinese students at different grade levels. The factor pattern of the CRMQ was invariant across primary, junior secondary, and senior secondary students in multisample CFA. As far as the scores on the four reading motivation constructs were concerned, students scored most highly on intrinsic motivation, followed by self‐efficacy, extrinsic motivation, and social motivation. Significant grade differences were found in all reading motivation constructs whereas only a few grade by gender and grade by school‐average interactions were found. Conclusion Consistent with previous studies in Western countries, the findings suggest that motivational decline is also a common phenomenon among Chinese students in Hong Kong. In addition, the pattern of motivational differences is generally consistent among students with different genders and from schools with different achievement levels. The implications of these findings for understanding Chinese students' reading motivation and for planning effective reading instruction to enhance their motivation are discussed.     

Ignorance of ignorance

I discuss the question of when knowledge of higher order ignorance is possible and show in particular that, under quite plausible assumptions, knowledge of second order ignorance is impossible.     

The effects of being spurned and self-esteem on depersonalization and coping preferences in kindergarten teachers: the case of Hong Kong

The primary objective of this study was to examine, based on a model of spurned helpers’ reactions: (a) the degrees to which kindergarten teachers in Hong Kong, China, experienced recurrent rejections of their offers of help (being spurned) by peer teachers; (b) whether being spurned by peers would induce depersonalization; (c) the ways teachers with higher or lower self-esteem coped with recurrent rejection; and (d) effects of coping in reducing depersonalization. A sample of serving kindergarten teachers in Hong Kong participated in the study. Their levels of self-esteem were first measured. Five months afterwards the extent to which they were spurned by their peers and the way they coped with such rejections were assessed. Another 5 months later the degrees to which they experienced depersonalization were measured. The results showed (a) that the teachers were fairly spurned; (b) that the more spurned the teachers were, the more depersonalized they were towards their peers; and (c) teachers with higher self-esteem and teachers with lower self-esteem coped with being spurned in different ways. The findings suggest that kindergarten teachers should be aware of recurrent rejection of their offers of help by peer workers and also the adverse effects of such rejection, and that administrators should provide training to teachers to assist them to deal with recurrent rejection of help by peers.     

Genetic moderation of contextual effects on negative arousal and parenting in African-American parents

A three-stage context amplification model was tested with a sample of 345 African-American parent-child dyads. The model combined the conceptual structure of stress generation with recent findings regarding genetic susceptibility. Because the 7R + allele of the dopamine transporter (DRD4) has the potential to enhance contextual priming and arousal, this allele was examined as a potential moderator of each stage of the amplification process. Particular attention was given to the hypothesized influence of parental negative arousal on valence of parent-child interactions. The literature on genetic susceptibility led to the hypothesis that DRD4 would moderate each stage of the model in a "for better or for worse" manner. The model was partially supported. DRD4 moderated effects at all three stages of the model and, as hypothesized, DRD4 moderated contextual effects on negative arousal in a "for better or for worse" manner. Effects on parent-child interaction, however, were moderated in a "for worse" manner only. These results indicate that parenting interactions may amplify the effects of positive and negative contexts in a stress-generating manner, and that a susceptibility framework captures the way in which DRD4 moderates the impact of context on negative arousal.
